ATTACHMENT IFOR ELECTRIC FLASILLAMPS.

Specification of Letters Patent Patented June 6, 191e.

Application filed November 24, 1915. Serial No. 63,212.

To all 'whom t may concern Be it knownthat I, HENRY ENN1s, citizen of the United States, yresiding at Layland, in the county of .Fayette and State of West `Virginia, have invented certain new and useful Improvements in Attachments for Electric Flash-Lamps, of which the followobstructed .the like.

pocket 'Hash lamp, a rod or needle mount#` ing is a specification, `reference being had to the accompanying drawings'.

This invention relates to an improved atg tachmentl for electric ash lamps, lthe primary purposebeingI to provide simpleandqf eilicient means for opening .the clogged or gas tube of miners"lamps and It is'a more particular object of the invention to provide in combination with a ed for lon 'tudinal shifting movement-upon one side o the lamp case and adapted to be y projected beyond theend of the ease adja- :mounting the sliding needle and y. and serviceable in actual use ,and capable of vfm'anufacture at relatively small cost.

With the above and other objects in view,f l

' ce1ve a needle or rod 1,7. A set screw'l8 m invention consists in the novel features ofy construction, combination and arrangement of parts to be hereinafter more fully deseribed,.elaimed and illustrated in the accompanying drawing, in which,

Figure l is an edge view of an electric Hash lamphaving my. improved attachment thereon illustrating the manner of using the same; F ig. 2 is a side elevation; Fig. 3 is a view of the opposite side of the lamp, ythe needle case being shown partly in section; Fig. 4 is a section takenon the line 4-4 of Fig..1; Fig. 5 is a section taken onf-,the line 5-5 of Fig. 2; and Fig. 6 isa detail per- '1 spective view'of the needle holder.

Referring in detail lto the drawing, 5

designates a pocket electric flash. lamp of any ordinary or well known type,the lamp case being provided in one end with a lamp bulb, indicated at 6. 5,

Upon one-side of thelamp case, a longiltudinal1y)disposed guide for the needle ,f

Ving fromthe inner end of holder to be` hereinafter referred to, is seconstructed from a -slngle Asheet of metal, indicated -at 7, and

cured. This guide is this metal sheet hasits central portion 1ongitudinally slotted or cut away as at 8, and A opening upon one ofthe end edges of the metal sheet.' Adjacent to the opposite longitudinal edges of this slot 8, tions of the metal sheetare .bent .inwardly toward yeach other, as shown at 9, Suchinwardly extending portions being spaced from .the contiguous portions of the metal `sheet atopposite'sides of .the slot 8, whereby ,the guide anges 10 are formed. The opposite portions of the metal sheet are forced toward each other, thereby bending or bowing the medial portion of the sheet extend- Y the slot 8 to the opposite end 'of the metal sheet into substanf tially semi-circular form, whereby a shield or housing 1l is produced. The wall of this housing'is provided with an opening 12 for a purpose to be later referred to. In the guide above described', a slide member is mounted, said member being formed from'a metal plate having an elongated in- 'termediatecylindrieal portion 13. and laterally extending flanges 14 which are engaged beneath the flanges 10 on the guide. It will be understood that the guide is soldered or otherwise securely attached to the side of the lamp case. In the cylindrical portion 13 of the slide member, a rod 15 is rotatably l mounted, one end of said rod being provided with a sleeve or enlargement 16 boredto reis threaded in the wall of said' sleeve for binding engagement with the needle to se-I form tothe 'slide member above described, is

securely fixed, and through the same the needle -17 extends.V

On the oppositeside of thelamp case, a suitable case or container 21 is secured to receive a number of needles 17 and a suitable screw driver, lwhereby the screw 18 may be readily loosened when it is neeessaiytoremove a needle and replace the same by an.

other. Y

22 designates the, switch button for the electriclamp, and 23 a sliding latch member the side pormounted on the case adjacent to the b'itto'ii-Iv and adapted to engage said button and hold the same in a depressed position during they use of vthe lamp.

In the practical use of the invention, the slide member is moved in its guide until the set screw 18 is disposed immediately beneath the'opening 12 in the housing 11. By means of a suitable screw driver, said screw may be tightened upon the end of a rod or needle` 17 which has been fitted through the guide 20 and into the bore of the sleeve 16. The operator holding the carbid lamp between the knees, now depresses the button 22 and moves the latch Q8 over the same so that the light rays from the bulb 6 will be thrown upon the end of the gas tube indicated at T, ot' the carbid lamp L. It will be understood that my invention may be used in connection with any ot' the various types ot' miners carbid lamps. After the needle 17 has been inserted into the end of the tube, tle knurled head 19 is engaged by the linger and turned whereby the needle is rotated and any obstruction or clogging of the gas in the tube is broken up or .dislodged so that the carbid will feed freely into the lamp chamber. After using the device, the Slide member is moved in the opposite direction in the guide 7 and the point of the needle drawn into the tubular guide 20. The housing or shield 1 1 covers the inner portion ot the needle and entirely eliminates any liability ot' the same being accidentally broken or distorted. l't will thus be seen that I have devised a very simple, serviceable and highly convenient attachment for the ordinary pocket electric flash lamp whereby the miners, without assistance, may readily and quickly fill their carbid lamps or open 4the gas t'eed tube thereuf; As the guide and protecting shield for the needle are constructed from a single sheet of metal, it will be appreciated that the device maybe manufactured and attached to the ordinary electric flash lamp at small cost. It is, however, to be understood that l reserve thc privilege ot mounting the sliding` needle f'or move- .ment upon the lamp case in various other ways than that specifically shown and described herein. lhc device is also suscepti-v ble of many other modifications in the several detail features thereof, and l. thereQ fore, also reserve the right of' adopting all such legitimate changes therein as may fairly fall within the spirit and scope of the invention as claimed.

llaving thus fully described' my invention` what l desire to claimand secure by l'iettcrs latcnt is l. 'lhe combination with 'an electric flash lam) of a valve cleaning needle slidablv Y mounted upon the exterior of' the lalup case messes ind adapted to be projected beyond a lamp bulb inthe end of the case, and means for irramially rotating said needle when the same' is projected to tSoperatiVe "position,

'2. The combination with an electric flash lamp, of a slide mounted upon the exterior of one of the side Walls' of the lamp case, a valve cleaning needle rotatably mounted in said slide, and means for manually rotating said needle when the slide is moved to project said needle to its opera-tive position.

3. The combination .with an electric flash lamp, of a slide mounted upon the exterior of one of the side walls of the lamp case, a valve cleaning needle rotatably mounted in said slide, means for manually rotating said needle when the slide is moved to project said needle'to its operative position, and a housing fixed to the wall of the case adapted to receive the point of the *cleaning needle when the same is moved to an inoperative position.

l. Thev combination with an electric flash lamp, ofi a slide member mounted exteriorly upon one side of the lamp case rhfor longitudinal movement, a rotatable holder mounted in the slide member, a valve cleaning needle fixed in said holder and adapted to be projected beyond the lamp bulb in the end oit' the slide lwhen the slide is moved in one direction. said holder and cleaning needle being adapted to be manual-ly rotated in the operative position 'ofsaid needle.

5. The combination with an electric flash lamp, of a guide secured to one side ofthe lamp case having a housing formed on one end, a slide member longitudinally slidable in said guide, a. holder rotatably mounted in the slide member, and means for detachably connecting a needle to said holder whereby said needle may be projected beyond the lamp bulb when the slide is moved in one direction. l

(i. The combination with an electric Hash lamp. of' a guide secured on one side of the i ingr when the slide's shifted in the opposite direction. c

ln testimony whereof I hereunto affix my signature in the presence of two witnesses.
